The Institute of Engineering Thermodynamics (LTT), founded in 1989, is part of the Department of Chemical and Biological Engineering and employs about 40 staff members. The research focus is the investigation and improvement of processes in energy and process engineering. A key issue is the optimization of combustion processes, spanning from an improved understanding of model flames to experimental studies of complex technical systems (e.g. combustion engines). A closely related field is the study of particle formation, on the one hand to reduce soot emission of practical combustion systems, on the other hand in the synthesis of nanoparticles with defined properties.
